ISL9768xIRTZEVALZ

Compact 2/3/4-Ch LED Drivers with Phase Shift Control Evaluation Boards

Description

The ISL97682IRTZEVALZ, ISL97683IRTZEVALZ and ISL97684IRTZEVALZ evaluation boards provide a complete testing platform for the ISL97682 (2 channel), ISL97683 (3 channel) and ISL97684 (4 channel) LED drivers.

The ISL97682, ISL97683, ISL97684 are Renesas’s highly integrated 2-3-4-channels LED drivers that are suitable for medium size TFT-LCD backlights. These parts can drive multiple channels of LEDs from inputs as low as 4V to outputs of up to 45V. They can also operate from inputs as low as 3V to outputs of up to 26.5V in bootstrap configuration (see Figure 26 for 3V operation).
